Sex partner transmission studies, presently underway, are also of high interest from the potential intervention perspective.
In part, this is due to the fact that partner transmission may occur during asymptomatic shedding [ 4] or unrecognised minor outbreaks.
These observations may indicate strong between partner transmission or may just as well point to the higher occurrence among lesbian women of certain BV-enhancing sexual practices (see below).
The model was modified to take account of high infection risk during early HIV infection associated with concurrent partner transmission - a weakness of the UNAIDS model for a country like Malawi with a high sexual partner concurrency rate.

These observations strongly suggest female-to-female between-partner transmission of BV.
The disproportionate HIV disease burden in MSM is explained largely by the high per-act and per-partner transmission probability of HIV transmission in receptive anal sex [ 28].
HIV in men who have sex with men (MSM) influences the overall HIV epidemic in both low and high income countries, which is related to high per-act and per-partner transmission probability of HIV transmission in receptive anal sex [ 1- 4].
Men who have sex with men (MSM) have a disproportionately high HIV burden, as a result of the high per-act and per-partner transmission probabilities during anal sex, and have higher rates of dual-variant and multiple-variant HIV infection than heterosexual people in the same settings [ 53].
Causes of the increased rates of STIs/HIV in young people are complex, however, the main reasons include biological factors, risky sexual behaviour patterns (early initiation of sex, premarital sex, bisexual orientation and multiple sexual partners), transmission dynamics and treatment-seeking behaviour [ 2].
In one observational study that included gay couples, treatment of the infected partner stopped transmission.
The Partners HSV-2/HIV-1 TranStudyion Study (Partners Study) is a phase III, placebo-controlled trial of daily acyclovir for genital herpes (HSV-2) suppression among HIV-1/HSV-2 co-infected persons to reduce HIV-1 transmission to their HIV-1 susceptible partners, which requires recruitment of HIV-1 serodiscordant heterosexual couples.
